auk_complete: Filter out incomplete checklists from the EBD

Description

Define a filter for the eBird Basic Dataset (EBD) to only keep complete checklists, i.e. those for which all birds seen or heard were recorded. These checklists are the most valuable for scientific uses since they provide presence and absence data.This function only defines the filter and, once all filters have been defined, auk_filter() should be used to call AWK and perform the filtering.

Usage

auk_complete(x)

Arguments

x

auk_ebd object; reference to EBD file created by auk_ebd().

Value

An auk_ebd object.

Examples

system.file("extdata/ebd-sample.txt", package = "auk") %>%
  auk_ebd() %>%
  auk_complete()
